4 maart 2013: Vertegenwoordigers van het Verenigd Konininkrijk (VK) hebben op 3 maart 2013 bevestigd dat hun land zal deelnemen in het European Extremely Large Telescope (E-ELT)-programma. Daarmee komt het totaal aantal ESO-lidstaten dat meedoet aan het E-ELT-programma op elf. Het Verenigd Koninkrijk is voor 16% partner van ESO en de nieuw aangekondigde investering beloopt zo'n 100 miljoen euro over de tienjarige constructieperiode. "Dit is een grote stap voorwaarts voor het E-ELT-project", zo licht ESO-directeur-generaal Tim de Zeeuw toe. "Het VK heeft al significant bijgedragen aan het ontwerp, en Britse astronomen en industrie zijn er goed op voorbereid om belangrijke bijdragen te leveren wanneer het project de constructiefase ingaat. Het VK heeft de ontwikkeling van de 'science case' geleid, maar ook instrumenten en optische en telescoop-systemen ontworpen, en bouwprocessen ontwikkeld. Het instrumentatieprogramma van de VK zal worden opgeleverd in nauwe samenwerking tussen Durham University, University of Oxford, University of Cambridge, STFC’s UK Astronomy ...

4 maart 2013: From 25 February until 1 March 2013, a major workshop on the future of instrumentation for the European Extremely Large Telescope (E-ELT), entitled Shaping E-ELT Science and Instrumentation was organised by ESO in Garching, Germany. The E-ELT is a revolutionary ground-based telescope — it will have a 39-metre main mirror, and will be the largest optical/near-infrared telescope in the world upon its completion in the next decade. There was great interest in the meeting — so much so that the original plan to hold the sessions at ESO itself had to be abandoned and a larger local venue used — and more than 180 astronomers from around Europe attended. This conference aimed to gather insight and input from the science community on the future course of action for the E-ELT, and to consider which instruments should be chosen to follow the telescope’s two first-light instruments. In particular, the possible future ...

1 maart 2013: The users of ESO facilities and the astronomical community in general now have an updated information source to help them keep up to date with the latest developments at ESO. The ESO Science Newsletter replaces the ESO Electronic Newsletter (Enews) and comes in a new format. It will continue and extend the role of the earlier publication. The continuity is also preserved through the editorship of Jeremy Walsh, who also edits the ESO Messenger. Along with other items of interest this edition includes the announcement of the ESO Call for Proposals for Period 92. The ESO Science Newsletter focuses on providing relevant and timely news to users of ESO facilities. It augments the information presented in public scientific press releases and the ESO Messenger with its in-depth articles and more general information on the organisation. It further aims at giving the readers links to relevant information available on the ESO ...

1 maart 2013: Op 13 maart 2013 wordt de Atacama Large Millimeter/submillimeter Array (ALMA) - het grootste astronomische project op aarde - geïnaugureerd. Daarmee wordt de overgang gemarkeerd van telescoop-in-aanbouw naar volledig operationeel observatorium. Om iedereen ter wereld de gelegenheid te bieden deze mijlpaal in de zoektocht van de mensheid naar het begrijpen van de kosmos, bij te wonen, zal er een live webcast worden gedaan vanaf de Operations Support Facility, het ALMA-basiskamp op 2900 meter hoogte in de Chileens Andes.

1 maart 2013: Het Nederlandse onderzoeksinstituut TNO heeft de laatste serie geavanceerde optische en mechanische systemen opgeleverd voor ESO's Very Large Telescope Interefrometer (VLTI). Met deze zogenoemde Star Separators zullen de toekomstige VLTI-instrumenten in staat zijn veel zwakkere objecten te observeren dan nu mogelijk is. De VLTI heeft een referentie-ster nodig om te corrigeren voor de constant veranderende atmosferische condities, waardoor hij met een extreem hoge precisie kan waarnemen. Op dit moment moet deze heldere ster ook het object van de waarnemingen zijn, waardoor astronomen beperkt zijn in het type ster waarnaar ze kijken met de VLTI. De nieuwe star separator-technologie maakt het mogelijk om twee objecten tegelijkertijd te observeren: een heldere ster om te corrigeren voor atmosferische storingen, en een zwakkere om echt te bestuderen. De correcties van het heldere object worden daarbij toegepast op het zwakkere. Dankzij deze ontwikkeling wordt het bereik van de VLTI, en de toekomstige instrumenten PRIMA en ...

27 februari 2013: ESO has produced and released a brochure containing information on the operation of the state-of-the-art instrumentation and facilities provided by the Very Large Telescope (VLT) at Paranal, Chile. The publication, entitled Operating the Very Large Telescope, describes the end-to-end science operations process: how observing time on the VLT is allocated, the efficiency and flexibility of the process for obtaining some of this time; what it is like to observe at a world-class site like Paranal, and how the data are collected, stored and shared. The VLT’s observing schedule, as well as the collection and archiving of the gathered data, is managed by teams at the ESO Headquarters in Garching, Germany, and at the different ESO sites in Chile. The strong link between Garching and Chile, ESO’s host country, has enabled the VLT to develop from an idea into a very efficient science machine. As well as the VLT operations, astronomers ...

26 februari 2013: On 14 March 2013, His Royal Highness, The Crown Prince of Denmark, will visit ESO’s Paranal Observatory in Chile accompanied by his wife, Her Royal Highness The Crown Princess. Denmark has been member of ESO since 1967, and the visit is part of the Crown Prince Couple’s official visit to Chile which will showcase several important cultural, industrial, health, environmental and scientific links between Denmark and Chile. The Crown Prince Couple will be meeting the press outside the Paranal Residencia at 20:45 CET/16:45 CLT on 14 March 2013. Members of the press are welcome to attend in person. To participate in this press and photo opportunity or to receive additional information, members of the media must obtain accreditation by contacting Mathieu Isidro (misidro@eso.org). A confirmation email will be sent and additional information will be provided only to the accredited media before the event. Accreditation will remain open until 8 March ...

25 februari 2013: A new brochure called The ALMA Universe detailing the design, construction, and use of the the Atacama Large Millimeter/submillimeter Array (ALMA) has been released by ESO in collaboration with its partners in the USA (NRAO) and East Asia (NAOJ). This publication describes the components and properties of the observatory that make it such a groundbreaking project, from its location to its revolutionary antennas, its specialised receivers and transporters, the powerful ALMA correlator supercomputer, its high imaging resolution and vividly clear astronomical images. The brochure also highlights some of the recent scientific discoveries made by ALMA. Although it is not yet fully functional, the array has achieved incredible results from just a partial arrangement of antennas during its Early Science observing phase. The ALMA brochure is available to view online in both English and Spanish.

22 februari 2013: The final front end for the Atacama Large Millimeter/submillimeter Array (ALMA) has been delivered to the observatory’s Operations Support Facility (OSF) in Chile, marking another milestone in the completion of the project. With one installed in each of ALMA’s 66 antennas, the front ends are the first step in a long chain of devices that receive, convert, process and record the astronomical data collected by the telescope. Each front end contains a set of extremely sensitive receivers, cooled to temperatures of just four degrees above absolute zero (-269 degrees Celsius), which detect the millimetre- and submillimetre-wavelength light that ALMA “sees”. Construction of the front ends for ALMA has been shared between the European, North American and East Asian partners in the project. Twenty-six of the total complement of 70 units were built at the European Front End Integration Centre, based at the Rutherford Appleton Laboratory (RAL) in the UK, including ...

21 februari 2013: A new and more powerful laser has successfully completed testing at ESO’s Paranal Observatory and has been formally accepted today. This new laser source is called PARLA and forms a vital part of the Laser Guide Star Facility (LGSF) at ESO’s Very Large Telescope (VLT). The laser is used to generate an artificial star about 90 kilometres up in the atmosphere [1]. By creating and observing such a bright point of light astronomers can probe the turbulence in the layers of the atmosphere above the telescope. This information is then used to adjust deformable mirrors in real time in order to correct most of the disturbances caused by the constant movement of atmosphere and create much sharper images. The new laser will greatly improve the reliability and flexibility in operating the LGSF. It uses similar technology to that which will also be employed in the four lasers of the future ...

19 februari 2013: An analysis of the number of peer-reviewed scientific papers published in 2012 using data from ESO’s telescopes and instruments has shown that ESO remains the world’s most productive ground-based observatory. More than 870 refereed papers using ESO data were published last year, a significant increase from the previous totals, and the most in ESO’s history. The number of papers using observations from ESO in 2012 was slightly ahead of those that used data from the NASA/ESA Hubble Space Telescope. About 70% of all the papers credited to ESO in 2012 employ data acquired using the Very Large Telescope (VLT)/ VLT Interferometer facilities, a fraction that has been consistently increasing over the past three years. Other facilities of the La Silla Paranal Observatory — including the survey telescope VISTA at Paranal as well as La Silla telescopes and instruments — have similar numbers to the previous year, and they alone nearly ...

15 februari 2013: This is the third installment of Chile Chill, a type of ESOcast designed to offer a calm experience of the Chilean night sky and ESO’s observing sites, undisturbed by facts or narration.

More Information The ESOcast is a video podcast series dedicated to bringing you the latest news and research from ESO — the European Southern Observatory. Subscribe to ...

31 januari 2013: with Dr. Andreas Müller (Universe Cluster) Time paces our life. We plan our schedules and our whole lives using it. In contrast to space, time has only one direction. It is constantly progressing, and we can not move back in time to undo mistakes from our past. However, according to Einstein's theory of relativity, time is not as unalterable as we experience it. Worse: when studying time, we have to consider what the whole Universe is doing, and under some conditions, time might even vanish. At next Café & Kosmos on 5 February 2013, Dr. Andreas Müller (Excellence Cluster Universe), author of the book Space and Time will discuss the mysteries of time with the audience. Exceptionally, Café & Kosmos will take place on the first Tuesday of the month (instead of the second) on 5 February. Also, please note of the new venue: Café & Kosmos will take place ...

22 januari 2013: The Summit of the Community of Latin American and Caribbean States (CELAC) and the European Union, the largest such event ever organised in Chile, was opened by President Sebastian Piñera today. The summit is a forum for the discussion of international affairs, with 61 heads of state and of government and their delegations invited, and with 1500 journalists from around the globe among the 3000 delegates attending. The summit is taking place between 22 and 27 January in Santiago. Astronomy will be a strong theme throughout the event, featured on various occasions on giant screens at the conference, through imagery of and from ESO’s observatories in Northern Chile. In the “Retiro” (“retreat”), the small room where heads of state will gather in an intimate setting to discuss international matters, a scale model of ESO’s European Extremely Large Telescope will decorate the centre of the room amidst constellations of the southern ...

22 januari 2013: On 22 January 2013 an ESO Industry Day was held at the Nicolaus Copernicus Astronomical Center in Warsaw, Poland. The meeting offered representatives of Polish companies and institutions information about ESO, and the potential opportunities — should Poland at some point join the organisation — to take part in its industrial activities. “We are delighted to have this opportunity to inform industry in Poland about ESO's current facilities and its challenging future plans,” said Tim de Zeeuw, ESO’s Director General, at the opening of the meeting. "Many exciting opportunities for ESO's Member States will appear in the near future, both for scientists and for industry, now that the E-ELT programme has been fully approved by the ESO Council." Modern astronomical telescopes and detectors are composed of many elements, which have to be designed by engineers and scientists, and produced by scientific and technological companies and institutes. Observatories need advanced infrastructure ...

22 januari 2013: ESO has extended its Science Outreach Network (ESON) further, by appointing national representatives for Russia, Romania and Latvia. The network now covers 27 countries, including the 15 member states. The core of the ESO website is now available in 19 different languages. This means that over one and half billion people can now access information about ESO and read about astronomical discoveries in their native language. Press releases are translated into 17 different languages, and many of the Pictures of the Week and announcements are made available in more and more languages. The nodes of the ESO Science Outreach Network act as ESO’s local media and outreach contacts with the general aim of promoting ESO's mission and demonstrating the many inspirational aspects of astronomy. They also serve as contacts between the media and scientists in their local area and can also be approached in connection with ESO’s projects and other ...

15 januari 2013: On 14–16 December 2012, the Geminid meteor shower made a spectacular appearance over ESO's Paranal Observatory in Chile. As the meteors showered down over the site, ESO Photo Ambassador Gianluca Lombardi was ready with his camera to record the spectacle. He spent over 40 hours recording the shower. The Geminids is a shower of shooting stars appearing to emanate from within the constellation of Gemini (The Twins). This shower occurs when the Earth cuts through the orbit of an asteroid named 3200 Phaethon, which happens once each year, in December. Particles in the trail of dust along the orbit of Phaethon burn up in our atmosphere, creating the brilliant, fast-moving points of light characteristic of meteor showers. This is the second installment of Chile Chill, a type of ESOcast designed to offer a calm experience of the Chilean night sky and ESO’s observing sites, undisturbed by narration. The Very Large ...

8 januari 2013: ALMA (the Atacama Large Millimeter/submillimeter Array) has begun a new and more advanced phase of science observations. This phase is known as Early Science Cycle 1, and will last until October 2013. The telescope’s power has been greatly increased: it will make observations with more antennas, spread over a greater distance, than ever before, and will use antennas from the Atacama Compact Array (ACA) for the first time. Although ALMA is still under construction, its first scientific operations began in 2011. This phase was known as Early Science Cycle 0. ALMA has already outperformed all other telescopes of its kind, and the unprecedented capabilities of the telescope have brought a first wave of exciting scientific results over the last year (see for example ann12101, eso1216, eso1239, and eso1248). The Cycle 0 observations started with just 16 of the telescope’s final complement of 66 antennas (which will be composed of a ...

4 januari 2013: With Prof. Dr. Andreas Burkert (Universe Cluster) A gas cloud identified as G2 is rapidly moving toward the centre of the Milky Way. In 2013, it will make its closest approach to the supermassive black hole that is lurking there. The cloud has a mass a few times that of the Earth, and it is observable with the ESO Very Large Telescope in Chile. Such an observation will be extraordinary for several reasons: first, the passage of a gas cloud near — or into — a black hole has never been observed before. Also, the evolution of the cloud is expected to be very fast. Theoreticians will therefore be able to check the predictions of their models very quickly. Prof. Dr. Andreas Burkert, from the Excellence Cluster Universe, will discuss the possible fate of this cloud with the guests of the next Café & Kosmos, on 8 January 2013. Please ...
